Its vague because it does effect both inbound and outbound traffic since the painting of the bridge isn't inbound/outbound dependent, its more location on the bridge dependent since both stories are being done at the same time. They also aren't painting the bridge from one side to the other, they started in the center and worked their way out. But it looks this year the extreme Charlestown and Chelsea sides & ramps will be done as the final step to complete the work.

Regardless, it's going to be a sucky commute all summer over the bridge. Thank gosh this is the last year.

It's less about paint, its more about removing the 1950s lead-ridden paint off the bridge before they can repaint it. This requires proper clean up and disposal. Plus trying to keep the bridge open during painting always extends the time period.
